Tagging school children with RFID chips is uncommon, but not new. A federally funded preschool in Richmond, California, began embedding RFID chips in students’ clothing in 2010. And an elementary school outside of Sacramento, California, scrubbed a plan in 2005amid a parental uproar. And a Houston, Texas, school district began using the chips to monitor students on 13 campuses in 2004.

It was only a matter of time. Radio frequency identification devices are a daily part of the electronic age, and are fast becoming a part of passports, libraries and payment cards, and are widely expected to replace bar-code labels on consumer goods.

And it appears that the educational move to Big Brother-style monitoring is motivated mainly by money, despite privacy and health concerns.
